                }             }         }     } }

protocol missing in url

string url = "http://api.worldweatheronline.com/free/v2/weather.ashx?q=campbell%20river&format=json&num_of_days=5&callback=rrr&key=xxxxxxxxxxxxxxxxxxxxxxx"; using (var webclient = new system.net.webclient()) {     var json = webclient.downloadstring(url); //this gives me exception error....dunno why.  }

and json string returnd api not correct, starts "rrr" (at time of writing of course)

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver.
